2 Claims.

The present invention relates generally to handling of coke oven doors and particularly to handling the same from a coke receiving car.

In coke production, it is necessary that coal 5 be confined in ovens for coke production and that there are doors on the ovens to remove the coke therefrom and that there is some means, usually a car or machine to operate the oven doors. The coke is very hot as it is discharged from the ovens and it is quite inconvenient for operators to get close to the hot coke or to an open oven while operating the car or the operating mechanism for oven doors. The ovens themselves emit considerable heat while the same are open and this also makes it quite inconvenient for operators to get close to an open oven while placing a, door onto the ovens or removing one therefrom.

The present invention aims to provide means whereby operators need not be subjected to the full inconveniences mentioned and to provide combinations of elements whereby the convenience and safety of operators is enhanced and to provide an efficient machine for operating the doors of coke ovens.

Objects of my invention are:

To provide coking plant machine with efiicient means whereby an operator is not required to work in great inconvenience around heat emitting parts of coking ovens 'or of hot coke.

To provide a coking plant machine with a door operating means to open and to close the doors of coking ovens while an operator remains on the car at a convenient distance from an open coking oven and from hot coke discharged from an oven.

To provide a coke carrying coking plant machine with an operators platform or run-way along the coke discharge side of the machine and above the discharge opening thereof and outwardly of the side of the machine to protect an operator on the platform against heat from hot coke in or being discharged from the coke carrying compartment of the machine.

To provide a coke carrying coking plant machine with a platform on an end thereof, outside of the coke carrying compartment to protect an operator or look-out on that end of the car from heat of coke in the coke carrying compartment of the machine when an operator is present thereon. To provide a coke carrying coking plant machine with an operators cab to protect an operator against weather conditions and against heat from open coking ovens and against heat from hot coke on the machine.

Tolocate this cab so that an, operator has a clear view all around and can diligently control the car as to its own movement and as to the door operating mechanism and the discharge mechanism of the coke carrying compartment of the machine. 5

To provide a coking plant machine with an oven door operating means which efliectively takes hold of such doors and removes the same from and replaces the same on ends of coking ovens and which is protected against flame and heat 10 emitting from an open oven.

To provide a coking plant machine with an oven door operating means which can pick up a door from a place away from an oven and put the same onto that oven or remove a door from an 15 oven and put the same in a place away from that oven.

To provide a coking plant machine with an oven door operating means which retains the oven door in correct relation to the front of an 20 oven during removal and replacement of the door from and onto the oven.

To generally combine various elements, new and old, to provide a coking plant machine with means which tend to promote efiiciency in the 25 machine and welfare of operators in the operation thereof.

Other objects will appear during the description of the car shown in the accompanying drawings or will become obvious or apparent upon'an in- 30 spection of the drawings and the specification.

In the accompanying drawings mentioned above:

Fig. 6 is a plan view of a car, similar to Fig. 1, but designed for horizontal or wide coking 55 i the run-way and vice versa.

therun-way. is inconvenient proximity to the The car B comprises the trucks l2 and I3 sup- 7 ported and adapted to run on the rails or tracks l4 and I5 and supporting the, chassis of the car and the hopper or coke compartment supported on the chassis of the car. 'The tops or levels of the tracks l4 and are located below the level of the oven floor a suflicient distance. so that.

the coke compartment is brought into such relation to the oven floor so that coke discharged from the oven will-move into the compartment during the discharge.

The platform, D is provided on one end of thechassis, endwise adjacent to the compartment 0 to provide a space and place for an operator. when necessary or desirable. This same operator may also operate the gates on the coke compartment when desired.

The platform or run-way E is supported on the chassis and extends along that side of the coke compartment whichhas the coke discharge gatesSZ thereon. The run-way E ends in closeproximity of the platform D so that an operator can conveniently step from the platform to The other end of operators cab F and can also be conveniently reached'from the ground by the steps IS. The railing ll protects an operator on the run-way.

The car Bis operated by the motor l8 mounted on the truck |3and the control means for the motor are located in the cab F.

The cab,F,,in this design, is mounted on the chassis,.a little distance from the end of the coke compartment to provide space for the weight compartment |9,which. is provided for the purpose of applying thereinto some weight or ballast I9 to counteract weight on one side of the car or. forces due to operating of the oven door to prevent tipping of theicar on the tracks. This ballast is required only under certain conditions and may be omitted when the car does not have any tendency to tip on the tracks.

' Inthis design, the oven door operating means is mounted on the top of the cab, suitable windows such as 6| being provided in the cab to permit an operator in the cab to see not only horizontally but vertically as well to observe conditions around the car and the operation of the door operating means above.

The door operating ram comprises the two axially movable, sidewise spaced members and 2| having the bracket structures 22 and 23 on one endthereof and the journal bearings 24 and 25 mounted on the corresponding bracket structures. The shaft 26 is journaled in the bearings 24 and 25 and has keyed ontothe ends thereof, to rotate therewith; the idler wheels 21 and 28 to be more definitely described herein below.

Theracks-ZB and 30 are secured to the respective bottoms of the members 20 and 2|. The pinions-3| and 32 mesh into the respective racks and are keyed onto the shaft 33, to rotate therewith, which shaft is journaled in the positionally fixed bearings: and 35-mounted respectively on the uprights 36 and 31. The ram rides on the pinions 3| and 32.

rotate therewith and is belted to the smaller wheel 39 on the shaft 40 in the cab by means of the rope or chain belt 4|. the smaller wheel 39 are operated by the hand wheel 42 in the cab. The guide wheels 43, 44 and 45 are journaled in respectivepositions to guide the ram into a definite path of movement.

The door operating motor 46 is mounted on the ram and operates the shaft 4'! rotatively. The shaft 4] is supported in the bearings 48 also mounted-on the ramand has keyed thereto, to rotate therewith, thedrums 49 and 50 in alinement with the above mentioned idler wheels 21 and 28, respectively, which are mounted on the shaft 26.

The drawings show two flexible members or elements between the door A and the drum 5!]. One ofsuch members oan-be used when the door is quite narrow. The specific construction ofthis flexible rnem'ber, more" specifically set-forth herein below, adapts the same'very well for single flexible elements since this specific structure prevents the chain fromrotative movements or twisting. on its own axis'and, when a single chain is used, will always hold the door in proper relation to an oven.

Each of the flexible elements shown has the cable part 5|, the chainpart 52, and the 53 in the chain part.

The cable parts 5| each has one endthereof secured to the corresponding drum 49 or 50. Each of these drums is quite wide to afford suflicient space for the cable part 5| to wind there on, preferably in single file to counteract any tendency of the cable part to climb either upon itself or upon the flanges of the drum. The other ends of the cable parts are secured to one end of the corresponding chain part 52.

The chain parts 52 pass over the idler wheels 21 or. 28, respectively. Each of these idler wheels may be grooved to suit the chain part 52 so that weight the same will be guided in a definite path. One

end of the chain part is secured to one endof the cable part 5| While the other end of the chain part is secured to the weight 53 shown in the drawings as being a ball so that there are no shoulders or the like thereon to catch other structure during a door operating movement thereof. This weight inclusion in the flexible element always puts a tension on the chain part even when no door or other weight is suspended thereon and always retains the links of the chain an oven door when the door is being opened andv to unhook the-same after the door is replaced on the oven.

The link 54 is open on one side so that the same canleasily'be hooked into the link 55 secured to the ball and into the link 56 secured to the upper end of the door A; (Fig. 4.)-

The'shield 51 is provided on and secured to the inner. endof the ram by welding or rivets or bolts-or any securing means which can safely withstand the flame and heat usually emitting from anopen coking oven, This shield is spaced from the ram structure by means of the stools 58 to provide'an air" space 59 between the shield The shaft 40 and which the ovens are built.

and the ram structure so that heat from the shield can not be transmitted directly to the ram structure and must pass through the heat insulating air space 59 before it can reach the ram structure.

The floors of coking ovens usually are arranged on a higher level than the ground upon Quite frequently an oven door must be deposited on the ground and away from its oven opening for various reasons and later again picked up from the ground for replacement on the oven. In devices of the prior art, there is no means for retaining the oven door away from the oven and at the same time be in a convenient place for the door operating mechanism to pick it up and to replace it on an oven or to remove the door from an oven and to move and deposit it in a place away from the oven for repairs or the like. In some cases special platforms have been built at the end of a battery of coking ovens for receiving doors which need repairing or the like but, with such platforms, it is necessary to use a locomotive crane or the like to bring the door from the platform to an oven door and then take hold of it by means of the door operating mechanism to put it onto the oven. Vice versa for removal of a door from an oven.

In the present invention, the chain part 52 always rights itself relatively to bring the door engaging hook thereon into position for easy engaging of the door either by the weight of the chain alone or with the weight therein. During the picking up or depositing of a door in a place away from an oven the cable part 5| may extend over the idler and the chain part may extend over the drum but this extension occurs only while the door is quite remote from the oven and the chain will right itself and the door thereon automatically as the latter approaches the end of a coking oven.

The shield effectively protects the ram structure particularly the journaled and moving parts and the lubricant for the journals due to the angular part 60 thereof which is bent outwardly to deflect flame and heat outwardly of the ram.

The combination of elements as arranged in the present invention provides a coking plant machine with various means and conveniences brought together conveniently located and easily and conveniently operated and easily and conveniently reached for operation so that the machine as a whole is not only highly eflicient but is also economical of structure and operation and presents convenience for operators of the machine.

Fig. 6 shows a plan view of Fig. 1 having the elements extended axially so that the operators cab can be located sidewise adjacent to the coke compartment and to the door operating mechanism so that an operator can conveniently oversee the operation of the coke compartment as well as the door operating mechanism and the path of the car in the same manner as in the device shown in Figs 1 and 2. In either case, the operators cab is adjacent to the coke compartment and to the door operating mechanism. In this case, the car as a whole is lengthened so that the cab can be placed between the coke compartment and the door operating mechanism.

Otherwise the above described structure and the below described operations are substantially the same. The same reference characters are used in both structures.

As to operation of the mechanism shown and described:

The car is guided by the tracks [4 and I5 and may be moved along the tracks by the motor 18 shown in geared relation to the driving axle and driving wheels of the car.

The platform D afiords a convenient means for a look-out or other passenger if requiredon the rear end of a power driven car.

The run-way E aifords a convenient means for an operator to have access to the doors on the coke compartment for operation of doors or otherwise. The run-way is located above the discharge part of the coke compartment so that an operator can have access to the discharge gates without great inconvenience from the coke compartment or reaching down from above the coke compartment and there is always considerable heat insulating air space between an operator on the run-way and the hot coke in the coke compartment.

The operators cab is located adjacent to the coke compartment and to the door operating mechanism; vertically adjacent in Figs. 1 and 2 and horizontally adjacent in Fig. 6 so that an operator can always have complete vision over the coke compartment and over the door operating mechanism and the path of the car through windows on all sides of the cab illustrated by the window 6! in one side of the cab.

An operator can conveniently step from the rear platform D onto the run-way and from there onto and into the cab F. Likewise, an operator in the cab can conveniently step from the cab to the run-way and from thence to the rear platform.

In that manner, full and complete control of the car is afforded and the combinations of elements, as herein combined, afford an efficient and convenient assembly into one easily controlled and efficiently operating car.

To remove a door from an oven, the ram is first extended into proximity of the door by means of rotating the hand wheel 42 accordingly and thereby rotating the wheel 39 which, through the connector 4i, rotates the shaft 33 and the pinio-ns 3i and 32 thereon and in mesh with the racks 2s and 30 and thereby moves the ram axially to any position desired.

When the ram is in proper position, the open ended link 54 is hooked into the link 55 on the oven door. The motor 46 is then started so that the cable parts 5! will be wound upon the drums 49 and 5t, respectively, and the chain parts 52 are thereby drawn over the wheels or idlers 21 and 2B and the door A will be moved upwardly and removed from the oven. The chain and cable parts of the flexible elements are arranged so that the chain parts never leave the idlers 21 and 28 during normal removal or re placement of the door.

However, when a door is to be picked up from or deposited on a floor below the level of the floor of the oven, the cable parts may extend over the idler wheels 2'1 and 28 and the chain parts may extend over the drums 49 and 58 during such quite obvious and appear to need no further special description herein.

Applicant is aware that changes and modi fications can be madein the structures and relations of parts herein shown and described within the spirit and intent of the present invention and of the appended claims; therefore, without limiting myself to the precise structures and arrangements of parts as shown and described.

I claim: 7
